Oxygen Rebreathing Unit Carbon Dioxide Absorbent Canister

An Oxygen Rebreathing Unit Carbon Dioxide Absorbent Canister is a component of an oxygen rebreathing system used in certain breathing apparatus, such as closed-circuit diving rebreathers or medical anesthesia machines.

The canister is filled with a substance called a carbon dioxide absorbent, which is designed to remove carbon dioxide from the exhaled breath of the user. As the user breathes out, the exhaled air passes through the canister, where the carbon dioxide is chemically absorbed by the absorbent material. The purified air, now with reduced carbon dioxide levels, is then inhaled again by the user.

The carbon dioxide absorbent material typically consists of a mixture of chemicals, such as soda lime or Baralyme, which have a high affinity for carbon dioxide. These chemicals react with the carbon dioxide, converting it into a solid or liquid compound that is trapped within the canister.

It is important to regularly monitor and replace the carbon dioxide absorbent canister, as the absorbent material becomes depleted over time and loses its effectiveness. Failure to replace the canister when necessary can result in increased carbon dioxide levels in the inhaled air, which can be harmful or even fatal to the user.

Overall, the Oxygen Rebreathing Unit Carbon Dioxide Absorbent Canister plays a crucial role in maintaining a safe and breathable environment for the user by removing carbon dioxide from the exhaled breath.
